This invention relates to a method of manufacturing surfacing material,and more parcolored blocks formed in representation of inlays.

A further object is to produce a method of fabricating strip or sheetmaterial of the above character whereby the surfacing strips or sheetsmay be readily, accurately and economically constructed.

With the foregoing objects in view, to-

gether with such other objectsv and advan-A tages as may subsequentlyappear, the inven-y tion resides in the steps and features hereinafterset forth and illustratedby way of example in the accompanying drawings,in which: 4

Fig. 1 is a perspective view of a block as initially formed preparatoryto assembling in interconnection with correspondingly formed blocks;

Fig. 2 is a view in perspective illustrating the manner of assembling aseries of blocks formed as shown in Fig. 1 to produce a line or row ofsuch blocks with alternate blocks formed of dierent colors.;

F-ig. 3 is a perspective view illustrating the manner of forming arelatively thin strip by severing the assembled blocks shown in Fig. 2;

Fig. 4 is a perspective view illustrating the manner of assembling aseries of rows of the assembled blocks such as shown in Fig. 2preparatory to forming panels of checkered character;

Fig. 5 is a perspective view of a panel. formed by severance from anassembled group of blocks as shown in Fig. 4.

In carrying out the invention,

I take a series of rectangular blocksjA of wood of suitable dimensionsand lform a dovetail channel B on one side of each of the blocks eX-tending throughout its vlength and opening to the ends thereof and Iform a rib Aor tongue C lof dovetail cross-section on the side oftheblock opposite that formed with the dovetail channel B. The blocks thusformed are assembled together in a row as shown in Fig. 2 by insertingthedovetail rib C longitudinally into a dovetail channel B on Vthe"adjacent block; the' walls-cf the-channel B andthe faces of the tongueC being of substantially corresponding dimensions yso that when theblocks are interconnected the contiguous faces thereof will bein closecontact. In assembling the blocks inthe manner described the contiguoussurfaces thereof are adhered to- Y gether by a suitable adhesive such asglue; the

assembled blocks being subjected to pressure l for example, as maple andwalnut;-the woods being selected according Y to the color effect to beobtained in the finished product.

In forming the tongue (j A sections of the block;

the block A, the channel B and are form-ed on the cross or buttthefother sides of the block then .comprising the radial section, andthe ends of the block constitutingthe A tangential section, which latterin the finished product will form the yfinished surface. Where it isdesired to'produce strips or moldings from the row of Vassembled blocks,n

the latter is Vsevered along its tangential section as indicated by the2, thus forming a strip as illustrated in-Fig. 3 consisting ofalternately colored blocks .in-

terconnected by (the dovetail joint between contiguous blocks, with thedovetail joint exposed on the top surface of the strip.

Where it is desired to form a panelof checkered appearance, a series ofthe strips,

as shown in Fig. 3, may be assembled side by dotted line D inFig. l

side in any desired arrangement but Where it is desired to form aplurality of panels of given dimensions such, for example, as a checkeror a chess board, a series of rows of the blocks may be adhered togetherside by side to form a rectangular fabricated block as shown in F ig. 4;the continguous rows of the blocks being arranged so that the blocks ofalternate colors of adjacent rows Will alternate relatively to eachother so that the end face of the assembled block will present acheckered appearance.

After thus forming the `fabricated block as shown in F ig. 4, it issevered parallel With the end face thereof as indicated by the dottedline E thus forming a checkered panel as shown in F ig. 5 which may bemounted on any suitable backing, such for example as a board formed ofseveral plies of Wood.

The strips and panels formed by ymy methyod may be of any desiredthickness and obviously may be made quite thin to serve as a veneerWhere desired.

The strips as formed in F 3 may be used either as moldings or inassembling panel Work, and may be employed as flooring, in which latterevent, they are formed v-Jith marginal tongues and grooves in a Wellknown manner, not necessary to be here shown.

Panels formed in accordance with my invention maybe utilized for variouspurposes as in the construction of game boards, table tops, doors,wainscoting or any vother panel Work or surfacing.

The exposed surface of the strips .or panels may obvious-ly be finishedinV any desired manner as by applying suitable surface iinishes and asby polishing'.

lllhilefl vhave shown and described the invention as applied to blocksofWood, it is obvious that the blocksv may .beformed of suitablecompositions.adapted to be severed to form thestrips or panels.l

kI claim:

The method of forming a terial consisting in forming With-a dovetailchannel on one side thereof and a dovetail rib on the side opposite thechannelled side, vsaid channel'and rib being formed across the grain ofthe block and ending in a plane parallel :to` the grain thereof,assembling a series of blocks thusformed in a -roW With 4contiguousblocks' interconnected surfacing -ma- ,blocks `of Wood by the dovetail`rib ,of oned'block.interengagA ing thev dovetail channel vof theadjacent block, said row of blocks being `formed of blocks ofalternatecolors and finally severing the blocks along a plane vparallelwith the grain thereof.
